Patent DE-3707558-A1 (DE)
Title: Belt conveyor
Inventor: HERZKE HARRY
IPC: B65G15/02
Filed: 1987-03-10
Abstract: A belt conveyor which consists of individual sections adjoining one another and has in each case an endless conveyor belt running over deflection rollers and/or deflection edges and thus forming an upper and a lower strand, which belt is held on at least one belt edge by means of guides which engage over beads arranged on the belt edges, the belt being movable relative to the guides, is to be constructed such that, on the one hand, the belt conveyor can be produced cost-effectively with an essentially unchanged action and such that, on the other hand, a multiplicity of different sets of dimensions of the belt conveyor are possible, in particular even in the deflection region. For this purpose, it is proposed, according to the invention, that the guide comprises in each case a holder of claw-shaped cross-section which engages over the bead, the holder being provided on the bead side with a recess which corresponds to the shape of the bead and is somewhat larger in cross-section, so that the bead engages, with play, in the recess and slides inside the recess, a supporting base, on which the belt runs, being provided on that side of the belt turned away from the holder.

Patent DE-3711634-A1 (DE)
Inventor: MEYZONNETTE JEAN LOUIS
IPC: G01S17/26
Filed: 1987-04-08
Abstract: The system cancels transmitter to receive breakthrough. A laser transmitter (1) and a modulator (2), send towards a target a modulated transmission wave and reception means comprise a first mixer (24) for mixing a local wave from transmitter (1) with the wave reflected by the target, to produce a beat wave OB. A detector (9) furnishes the useful signal. Means (26) taps a fraction of said transmitted modulated wave, and modulators (7) and (8) modulate in phase and in amplitude said tapped wave to produce a correction optical wave OC. A second mixer (15), mixes said beat wave OB with the correction optical wave OC modulated in phase and in amplitude. A control circuit (10) for controlling said phase and amplitude modulation means (7 and 8) receives said useful signal so as to control said phase and amplitude modulation means (7 and 8) to eliminate the stray components that are superimposed on said beat wave, by minimising the amplitude of the useful wave SU. <IMAGE>

Patent DE-3714973-A1 (DE)
Title: Apparatus for manufacturing blind slats
Inventor: ARCHER JOHN
IPC: B21D53/00
Filed: 1987-05-06
Abstract: The manufacture of blind slats (1) serving as blind components has proved difficult within the limits of mass production since, because of the slats being relatively thin and curved in cross-section, there is a danger of damage being caused directly by the punching of an edge recess (2), of a slot (4) and also by the moulding of a bent section (3). The bent section (3), the slot (4) and also the edge recess (2) serve to guide cords whereby the blind can be raised or the slats turned. An apparatus according to the invention for manufacturing blind slats is characterised by, in each case, a press component (17) subjected to spring tension, a bending device (10) and punching elements (8, 9) which cooperate with a die (7) to the extent that during the manufacturing process the slat (1) is forced by the press component (17) against the die (7), that is before the bending and punching processes are initiated by the mentioned bending and punching tools. An apparatus suitable for the damage-free mass production of blind slats is obtained in this way. <IMAGE>

IPC: E21C25/10
Filed: 1987-05-15
Abstract: Cutting drums which carry a frustoconical end ring at the back of the cut and are fitted with driver strips cannot be pushed axially into the working face. The aim of the proposed cutting-drum design is to solve this problem. With the aforesaid cutting-drum type, it is intended to enable the cutting drum to penetrate into the working face in a boring (drilling) manner and also enable mineral to be parted by means of drum movements parallel to the working face. To this end, the working-face-side front surface, located inside the end ring (7), of the cutting-drum body (2) is of frustoconical design projecting towards the working face. But it does not protrude beyond the large base area of the frustoconical end ring (7) and defines with its circumference (10a) the openings (12) which are located in the circumference of the frustoconical end ring (7) and lead into the intermediate spaces of the driver strips (8). The circumference (10a) of the frustoconical front surface of the cutting drum and the radial boundary edges (13) of the openings (12) are fitted with cutting tools (9) to improve the flow of excavated material. <IMAGE>

Title: Central four-way conditioning device for room air having tubular construction units
Inventor: HILBERS HEINRICH DIPL ING
IPC: F24F3/00
Filed: 1987-07-31
Abstract: The invention relates to a device for conditioning room air. The unit consists of a plurality of components which are of tubular design. The pressure-stage apparatus provided as basic unit consists of the radial/axial fan for supply air as well as a radial/axial fan for circulation air, which convey the main air current on a common drive shaft with a drive motor. The air distributor provided between the radial/axial fans consists of the double restricting device which is axially displaced by means of a servomotor such that the air openings located in the restricting plate are opened or closed in the axial and radial direction simultaneously in accordance with the air state. The individual construction units for air conditioning are interconnected by means of sleeves and can be easily exchanged. The air-conditioning device can be used in the area of high-speed ventilation on account of the flow-related advantages. The lightweight construction and the design with a simple flow acting in the same direction leads to savings in the building dimensions and to a reduction in weight. The mounting arrangement in any desired position is possible. This results in advantages in the use of the device. There is greater cost-effectiveness of manufacturing and maintenance.

Title: Thermal printer with a thermal print head arranged on a movable slide and an ink-ribbon cartridge
Inventor: LANGE HEINZ
IPC: B41J35/08
Filed: 1988-03-15
Abstract: In thermal printing mechanisms having thermal print heads which have individually heatable heating elements for producing individual printing dots on the recording medium by means of a thermal transfer ink ribbon (7), it is necessary for the ink ribbon (7) to be guided tautly in the printing region. In these printing mechanisms, an ink-ribbon cartridge (8) is also provided, which is designed as a disposable article when the ink ribbon (7) has been used up. Such known ink-ribbon cartridges (8) have a transporting roller which drives the ink ribbon (7) with frictional engagement and can be coupled with and decoupled from a drive element in the cartridge receptacle. The invention is based on the object of simplifying the ink-ribbon cartridge (8) and making it less expensive. This is achieved in that a transporting roller (16), which transports the ink ribbon (7) with frictional engagement, is arranged in the printing region on the cartridge receptacle (19) so that it can be driven by a motor, in that the piece of the ink ribbon (7) located between the outlet and inlet apertures can be tensioned and held on the cartridge housing (60) by means of a holding device in such a way that the ink ribbon (7) passes without contact behind the transporting roller (16) when the cartridge (8) is fitted onto the cartridge receptacle (19) and can only be pulled out of the holding device and brought into frictional engagement with the transporting roller (16) by turning the winding spool (30) in the winding direction.

Title: Method and device for controlling the lye pumping-off operation in washing machines
Inventor: ANKELMANN WOLFGANG DIPL ING
IPC: D06F33/47
Filed: 1988-07-27
Abstract: The lye-pump feed capacity must correspond to the quantity of waste spinning water occurring. In appliances available on the market, the lye-pump is controlled via a program-switching unit. The "on" and "off" times of the lye-pump are not in synchronism with the quantity of waste spinning water occurring, and therefore the idling pump sucks up air and does not transport the lye away. As a result of the solution according to the invention, the lye-pump feed capacity is matched exactly to the quantity of waste water occurring. A throughflow sensor (11) is mounted on the feed side of the lye-pump (5). It signals are fed as input signals (12) to an electronic circuit (10). On the basis of an actual/desired-value comparison, the drive motor (8) of the lye-pump (5) is briefly switched off and on several times until a predetermined minimum waste-water feed quantity is exceeded. The method and device according to the invention are especially suitable for use in domestic washing machines and, moreover, for dishwashers. <IMAGE>
